Answer:B
Step-by-step explanation:
So we can use the Pythagorean's Theorem to figure this out.
The Pythagorean's Theorem is: a^2 + b^2 = c^2
Basically, leg1 squared plus leg2 squared = hypotenuse squared
So the two legs are 12 and 16, so we can put them in the equation.
12^2 + 16 ^ 2 = hypotenuse ^2
Or,
144 + 256 = hypotenuse ^ 2
400 = hypotenuse ^ 2
Then we can do the square root of 400 to find the hypotenuse.
√400 = 20
The length of the hypotenuse is 20 centimeters.

Answer: $30.40
Step-by-step explanation: If you know that the original price is $38 and it was marked down by 20%, you could multiply the original price by ".80". This represents 80% of the original cost, since it was marked down by 20%. By multiplying $38 by .80, you end up with $30.40.
